Are you talking about frontrunning? That happens in both blockchain-based trading systems as well as private systems, but on the blockchain it's easy to see that it's happening and what address is doing it (transparency). Anyone can frontrun on the blockchain, so it becomes a much more level playing field.

Front running on the blockchain can also be combatted through various approaches like a commit and reveal scheme, but that slows down the market and hasn't been adopted widely

The point I made: the shitty in transparent things normal people don't know about are also happening at Bitcoin.

Bitcoin didn't solve any of this.

Frontrunning on the blockchain is transparent. Bitcoin doesn't have exchanges so trading is happening on private exchanges, but other blockchain have decentralized exchanges where frontrunning is obvious and you can often reverse engineer the strategy and sabotage or frontrun the frontrunner.

Frontrunning is far more transparent on decentralized exchanges than anywhere else.
